[ARM] 3595/1: ixp4xx/nas100d: Board support for new LED subsystem

Browse Source 
Patch from Rod Whitby

This patch implements NEW_LEDS support for the IOMega NAS100d.  The
NAS100d has three LED indicators, which are the only form of output
for an unmodified device - there is no keyboard or display on an
NAS100d.  For an NAS100d which has been modified to bring out the
serial port console, it is important to register that device first
separately, to enable debugging of other device support.
